Japanese judoka Abe Hifumi and his younger sister Abe Uta have both won gold medals at the World Judo Championships in Doha, Qatar.
On Monday, Abe Hifumi, the gold medalist in the men's 66-kg division at the Tokyo Olympics, beat Vazha Margvelashvili of Georgia in the quarterfinals. Margvelashvili took the silver in Tokyo.
In the final, Abe beat longtime rival Maruyama Joshiro, who was the runner-up in the race to represent Japan at the Tokyo Olympics.
This is Abe's fourth world title and the second in a row. He ties Yamashita Yasuhiro, president of the All Japan Judo Federation, and others in the number of world championships won by a Japanese male judoka.
Abe later said he believes he has proved himself to be an Olympic champion.
Meanwhile, his younger sister Uta won the gold in the women's 52-kg division, as she did at the Tokyo Olympics.
Like her brother, she now has the world title for the fourth time, and the second in a row.
